Abstract :
In the past years, several methods combining FDTD-like algorithms and wavelets have been developed in order to reduce simulation times. We present a method that directly transforms Yee´s three-dimensional FDTD-algorithm into the wavelet domain at arbitrary scale. We derive an analytic and stable multigrid-like method and present simulation results.
